ETHOD OF AIR Jan. 12, 1932 Patented Jan. 12, 1932 PATENT. orrlc'a MAXGO'IH, OF MUNICH, GERMANY METHOD OF, AND MEANS FOR, INJEGTING FUELWITHOUT AIR INTO INTERNAL COMBUSTION ENGINES v 1 Application filedFebruary 28, 1928, Serial No. 258,190, and in Germany December 23, 1926.

Applications have been filed in Germany I December 23, 1926, Serial N 0,102,275 and in jected into an internal combustion engine after the airhas been compressed and forced throu h an inlet into a chamber outsidethe cylinrir, the fuel being then projected, from the cylinder side,against the dividin wall between the said chamber and the cy 'nder, insuch manner that the greater part of the fuel is flung back by the saidwall, but that a small part enters the said chamber and is ignited, theburning of this fuel serving to drive the remaining air back to thecylinder, where it is energetically mixed with the fuel, and completelyburned.

Preferably I arrange that the air chamber referred to is made readilydetachable; the dividing wall may be part of the detachable chamber orit may be a separate member, which is adjustable for varying orregulating the angle at which it is struck by the fuel. The opening oropenings in the dividing wall may be regulatable.

The air chamber may be made in two parts, provision being made forcharging the same easily, for example for the purpose of substituting achamber of another size. The chamber may be insulated to maintain it atthe proper temperature.

The invention is illustrated in theaccompanying drawings in which Fig. lisa fragmentary vertical section of an engine cylinder embodying theinvention; Figs. 2 and 3 are vertical sections of two modified forms ofmeans for controllin the entrance of fuel into the ignition cham er andFig. 4 is a horizontal section through the main control wall z'.

An example of apparatus according to the invention is shown in Fig. 1showing part of a water-cooled cylinder a, with a c linder head I) andpiston 0. The piston pus es the compressed air from the compressionchamber e of the cylinder into a globular chamber f'fitted to thecylinder head. The chamber 7 consists of two parts 9 and k, the part ithaving a neck, which is inserted into a hole in the c linder head, andin which there is. a per orated dividing wall '5. That part 9 is screwedinto the cylinder head.

Fuel is injected by means of a water-- I cooled nozzle (13 set obliquelyin relation to the wall 2', so that the greater part of the fuel isflung back towards the piston, and is vaporized, making a rich mixturein the chamber e. The small quantity of fuel penetrating into the bodyof compressed air in the chamber f becomes ignited, and drives out theair, which enters the chamber 6,

where complete combustion takes place. As

the combustion takes place mainly in the chamber e the chamber remainscomparatively cool, and there is ittle or no carbonization therein. Theperforations of the wall 2' are not liable to become clogged. Themaximum temperature occurs closely to the wall 2', which is favorable tothe progress of combustion. The combustion diagrams made with referenceto various engines operating according to the invention have indicatedvery satisfactory conditions in regard to combustion.

Fig. 2 illustrates a modification of fuel control means for the ignitioncylinder, wherein the perforated wall 11 is adjustably mounted by meansof a spindle is associated with the wall at a nonrectilinear angle tothe plane thereof, the, spindle passing through a bearing block or bossZ and being rotatable by means of a handle m. Figs. 3 and 4 illustrate amodificatiqn vherein the sizes of the perforations in wall '5 may becontrolled by means of the auxiliary perforated wall '5 movablyassociated with the wall 71 and carried by the spindle passing throughthe block Z and rotatable by means of the handle m Having nowparticularly described and ascertained the nature of my said inventionand in what manner the same is to be performed, I declare that what Iclaim is 1. In an internal combustion engine, a cylinder, an ignitionchamber at the head thereof and having an opening directed toward saidcylinder, means alongside of the cylinder for projecting fuel towardsaid opening, and means at said opening for allowingpassage of some ofsaid fuel into said ignition chamber but deflecting most of said fuelinto said cylinder; said last-named means comprising a perforatedwallacross said opening and a 5 flange about said wall. a y

.2. In an internal combustion engine, a cyl-' inder, an ignition chamberat the head thereof and having an opening directed toward said cylinder,means alongside of the cylinder for projecting fuel toward said opening,and means at said opening for'allowing pamage of some of said fuelintosaid ignition chamber but deflecting most of said fuel into saidcylinder; said last-named means comprising a perforated wall arranged insaid opening at a non-rectilinear an 1e to the direction 0 fuelrojection and a ange about said wall.

3. an internal combustion engine, a cylinder, an ignition chamber'at thehead thereof and having an opening directed toward said cylinder, meansalongside of the cylinder for projecting fuel toward said opemng, a wallat said opening for deflectin most of said projected fuel into saidcylin er, and means for adjusting said wall to control the direction ofdeflection.

.4. In an internal combustion engine, a cylinder, an ignition chamber atthe head thereof and having an opening directed toward said cylinder,means alongside of the cylinder for projecting fuel toward said opening,a perforated wall at saidopening for deflecting most of said projectedfuel into said cylinder while permitting some of the fuel to enter saidignition chamber, and means for varying the sizes of said perforations.J 7
